Modeling Subject Areas

I may be missing something but I can't find the subject area object options in the current version of ERStudio. Looking to model a two level subject area structure that I can hang entities off of. Thanks much.

You could use shapes to model the subject areas. Have the shapes contain the tables/objects you want and then you can use the line shape to show relationships.

Another option would be to use Business Data Objects. Use the Business Data objects as your containment and then have tables within it. The benefit of this is that you can minimize the BDO and still see the relationships going out.

I know I can contain entities within a business object but don't seem to be able to contain a business object within a business object. Looking to have a Major Subject Area that contains a Minor Subject Area that contains entities structure.

are you talking about the Shape containing the BDO? If you right click on the shape, you can choose containment -> enable and anything you put on the shape should be contained there. So when you move the shape, everything in it will move with the shape.
